Pecíolo em uma angiosperma


Em botânica, chama-se pecíolo (por vezes também denominado estipe) a um caule que fica entre a bainha e
o limbo ou lâmina das folhas das plantas vasculares. Eixo de sustentação do limbo, geralmente cilíndrico. Algumas vezes possui uma expansão laminar, sendo então denominado pecíolo alado, como nas laranjeiras.


Em muitas espécies de plantas, as folhas não possuem pecíolo e chamam-se folhas sésseis, já em outras o pecíolo se liga diretamente ao centro do limbo chamando de peltada.

Refactoring coordinates for Minecraft Pi buildings written in Python

Image
0 $begingroup$ I'm fairly new to coding and I wrote this script in Python for a house with a roof in Minecraft Pi. I've found different ways to write the coordinates to make the code base shorter, but I'm wondering if it is possible for me to refactor it any further so I don't have to list each coordinate line by line. import mcpi.minecraft as minecraft import mcpi.block as block mc = minecraft.Minecraft.create() p = mc.player.getTilePos() mc.setBlocks(p.x+1, p.y, p.z+1, #Main structure starting coordinates (DO NOT ALTER) p.x+19, p.y+4, p.z+6, #Structure size/coordinates (Alters cube size) block.STONE_BRICK) mc.setBlocks(p.x+2, p.y+1, p.z+2, #Hollowing out main structure interior p.x+18, p.y+3, p.z+5, block.AIR) mc.setBlocks(p.x, p.y...
